How does the story of Noah relate to God's saving power?

In Hebrews 11:7, we see that by faith, Noah warned of things not yet seen and prepared an ark for the saving of his household. This account echoes the sovereignty of God, as He used Noah, just one man, to deliver His message of impending judgment and salvation. Noah's actions served as a testimony to his faith, demonstrating that obedience to God can lead to salvation. Moreover, the flood narrative exemplifies the idea that God's plan of salvation often works through the faithfulness of individuals, reinforcing that, like Jonathan and his armor-bearer, one obedient servant can catalyze divine salvation for many. Thus, Noah’s story encourages believers to trust in God’s use of the few to fulfill His eternal purposes.
